Title: Character recognition device
Inventor: MATSUI SHINJI
IPC: G06K9/62
Filed: 1991-11-11
Abstract: PURPOSE:To improve the recognition precision by attaining a multilevel discrimination processing without increasing a circuit scale. CONSTITUTION:The feature pattern of a character picture is extracted as a multi-dimensional vector by a feature extracting circuit 31, and compared with a dictionary pattern stored in a storage device 33 for a dictionary by a pattern matching circuit 35 in order to search the similarity. And also, a code indicating a discrimination level is added to the similarity, and the obtained similarity data are rearranged in the order of the similarity by a sort circuit 39 in order to operate a discrimination processing. Moreover, the discrimination processing of the feature pattern extracted from the character picture by a different method is repeated by using the same pattern matching circuit 35 and circuit 39.

IPC: G06F9/46
Filed: 1991-12-06
Abstract: PURPOSE:To prevent a fault from extending over the whole system by executing a feedback immediately to an operating system (OS), when a program fault is generated, and retaining a transaction being in an actuation waiting queue registering instruction without initializing it. CONSTITUTION:At a normal time, an OS fetches a transaction A 20 registered in an actuation waiting queue A 10, registers it in an executing queue 13, and simultaneously, initializes an OS-APL communication area of the transaction A 20, actuates an APL task actuated by the transaction A 20, and in an execution process of the APL task, a catching request of the transaction A 20, etc., are executed to the OS. In such a state, when a program fault is generated, a feedback is executed immediately to the OS, and the transaction A 20 registered in the actuation waiting queue is retained without initializing it. Accordingly, a service of an input received already is not rejected, and it is prevented that the program fault extends over the whole system.

Title: Information recorder
Inventor: YOSHIMARU TOMOHISA
IPC: G11B20/10
Filed: 1988-12-23
Abstract: PURPOSE:To keep a recording capacity large and to alleviate recording conditions on an outer circumferential part by expanding gradually pit intervals toward the outer peripheral side. CONSTITUTION:Pits are formed in order of a0, a1,... on a track with a radius (r), and their pit pitch is l. On a track with a radius 2r, pits are formed in order of b0, d1, c2(d2), d3..., and their pit pitch is in between a characteristic line of a constant angular velocity system and a characteristic line of a constant linear velocity system as l < pit pitch < 2l. A data transfer clock is changable in a step form in accordance with a radius position. By this constitution, the design of a variable divider circuit is facilitated. In this case, a setting data for changing the data transfer clock in the step form with individual track numbers as previously determined is prepared in a conversion table formed in a ROM inside of a control circuit. By this method, the access time is speeded up with a large recording capacity, and the recording on the outer circumferential part can stably be performed.

IPC: H01L27/118
Filed: 1989-12-15
Abstract: PURPOSE:To increase the number of gates capable of being loaded on chips in the same size without augmenting skews and decreasing working speed by using an SPL circuit as a gate having a large load and an NTL circuit as a gate having a small load. CONSTITUTION:Striplike cell regions 4a and channel regions 4b are formed alternately. Signal conductors connecting each gate are disposed in the channel regions 4b. Macro cells 5 in which two SPL gate cells 5a and two NTL gate cells 5b are combined are arranged in a lateral line in the cell region 4a.

That is, the NTL gates are employed as gates having small load capacitance CL, and the SPL gates are employed as gates having large load capacitance CL. Accordingly, when the NTL gates have small load capacitance, working speed thereof is increased fast enough not to cause any skew.

Title: Synchronizing signal detection circuit for multibeam optical disk device
Inventor: NAGAI SATOSHI
IPC: G11B11/10
Filed: 1989-12-14
Abstract: PURPOSE:To prevent the lack of a synchronizing signal in a reproduction signal by the failure to detect this by delaying the synchronizing signal when at least a specific bits of the reproduced synchronizing signal from plural light means are coincident with a reference synchronous signal, taking the AND of this output and a window pulse and making it to be the normal synchronizing signal. CONSTITUTION:An input data is applied to an exclusive NOR gate (28-1)-(28-24), and the number of bits which is coincident with the reference block synchronizing signal is calculated by a counter 29. A pulse formation circuit 33 forms a window pulse with a (b) bit of an arbitrary width which starts from the signal when the counter 29 detects an all-bit coincident synchronizing signal which all bits are coincident with the reference synchronizing signal. And, for each of the reproduced synchronizing signal, synchronous signal is generated when it is detected that at least (q) bits (0<q<p) is coincident with the reference synchronizing signal, and the generated synchronous signal is delayed (c) bits (c=b/2). The AND of this output and the window pulse is obtained, and this output is made to be the normal synchronizing signal for each light beam. Thus the lacking by the failure to detect the block synchronizing signal can be prevented.

Title: Registering method for screen printing
Inventor: UENO TAKAHIRO
IPC: B41F15/26
Filed: 1987-12-21
Abstract: PURPOSE:To facilitate the registering of a printer table relative to a printing plate holder by emitting beams of light onto a base plate placed on the printer table through holes having a specific diameter and provided in the printer table, and then by registering marks imparted on a screen to the beams of light so emitted. CONSTITUTION:Holes 3a, 3b are provided on a table 3 at two diagonal positions, and light from light sources 4a, 4b is collimated via optical systems 5a, 5b so as to be allowed to pass through the holes 3a, 3b onto the rear side of a base plate that is fixed to the table 3. In a case where the base plate is not present at the positions where the holes 3a, 3b are provided, beams of light are directly emitted onto a screen mounted on a printing plate holder. Register marks are provided on the screen at positions coinciding with the holes 3a, 3b and a pattern is formed on the screen on the basis of these register marks functioning as reference points. In this construction, the registering of the base plate relative to the pattern on the screen can be effected by registering the register marks on the screen to the beams of light emitted through the holes 3a, 3b.

Filed: 1997-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent a dot gain which decreases the resolution from generating by a method wherein by a bright pixel which is bright or slightly tinted with a color, a color ink pixel or a gray scale black pixel is surrounded. SOLUTION: An ink jet printer has a printing head, and a printing is performed by using a phase variable ink.

Bright or slightly tinted ink drops 32 work in a manner to surround the adjacent non-white solid ink drops 31, 34, and prevent the ink drops 31, 34 from expanding to a part which is a non-printing area. In the same manner, the depth of the clear or bright gray ink drops 32 may be not less than 1 pixel along a border in a manner to surround the edge of the solid ink drops.

Filed: 1992-11-10
Abstract: PURPOSE:To easily and surely detect the size of a cassette by detecting the size of the cassette transferred by a transfer device between a light emitting device and a light receiving device. CONSTITUTION:When the cassette housed in a cassette housing part 13 is transferred by a cassette transfer part 14, the cassette is pulled out from the cassette housing shelf 13 by the holding part 42A and the holding member 43 of a slide arm 42. At this time, the size of the cassette is detected by photosensers 30A-30E and 31A-31E. That is, when the transferred cassette is an L cassette, the cassette becomes clear as the L cassette 23L since all of the irradiation beams LA1-LA5 of the photosensers are shielded. Similarly, the sizes of the transferred cassettes are discriminated as an M cassette 23M and an S cassette 23S since the irradiation beams LA2-LA4 and LA3 are shielded respectively among the irradiation beams LA1-LA5 of the photosensers.
